Currently, the active perfmon is not\nstopped during destruction, leaving the `v3d->active_perfmon` pointer\nstale. This can lead to undefined behavior and instability.\n\nThis patch ensures that the active perfmon is stopped before being\ndestroyed, aligning with the behavior introduced in commit\n7d1fd3638ee3 (\"drm/v3d: Stop the active perfmon before being destroyed\")." } ], "metrics": [ { "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "baseScore": 7.8, "baseSeverity": "HIGH" }, "scenarios": [ { "lang": "en", "value": "AV:L - The vulnerability is reached exclusively through DRM ioctls (`V3D_PERFMON_CREATE/DESTROY`, `V3D_SUBMIT_CL/CSD`) on the local `/dev/dri/renderD*` device node. No network or physical component is involved.\nAC:L - No race is required — the attacker performs a deterministic, fully self-controlled sequence (create perfmon, submit a job with it, wait for the fence, destroy it, submit another job) and additionally controls the freed object's slab size via `ncounters` and the reclaim window before the stale pointer is used.\nPR:L - The perfmon ioctls are `DRM_RENDER_ALLOW` with no `DRM_AUTH` or capability check, so any local unprivileged user with render-node access (standard for GUI/GPU users on Raspberry Pi OS, Android apps, embedded/kiosk V3D systems) can trigger it. No root or DRM master privilege is needed.\nUI:N - A single unprivileged process performs every step itself via ioctls on its own file descriptor. No victim action or interaction is required.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The stale `v3d->active_perfmon` is dereferenced after `kfree()`, reading `perfmon->ncounters` and `perfmon->values[]` from a slab slot the attacker can reclaim with a chosen object; `v3d_write_performance_query_result()` and `v3d_perfmon_get_values_ioctl()` can copy such freed-memory contents back to userspace, giving kernel memory disclosure.\nI:H - `v3d_perfmon_stop()` writes into the freed object — `mutex_lock()` stores the `current` task pointer into the owner field and `perfmon->values[i] += V3D_CORE_READ(...)` performs a read-modify-write at attacker-chosen offsets — over a slab slot of attacker-chosen size that can be re-occupied by a victim object, yielding a corruption primitive suitable for privilege escalation.\nA:H - Dereferencing the freed perfmon reliably oopses the kernel; the sibling fix for the identical root cause documents a fatal paging fault in `__mutex_lock` from the `v3d_bin` scheduler kthread, killing the GPU pipeline and panicking the machine." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [
